Ren Ventura

Allow your users (except for administrators) to manually delete their own accounts. It uses the <a href="http://t4t5.github.io/sweetalert/" rel="nofollow ugc">Sweet Alert</a> jQuery plugin for slick-looking alerts and prompts.
By default, this plugin adds a button to a user’s profile page in the wp-admin. You can also add a delete button to any page or post using the <code>[wp_delete_user_accounts]</code> shortcode.
NOTE: Delete buttons are not displayed when logged in as an administrator. This is done to protect against locking yourself out of your site. To see the delete button, you’ll need to log in with an account that does not have the administrator role.
For more technical info, including available hooks (actions and filters), please see the plugin’s <a href="https://github.com/renventura/wp-delete-user-accounts" rel="nofollow ugc">readme file on Github</a>.

Rownd is a user authentication and account platform that helps you convert more visitors to your website into actual (paying) customers.
We’re focused on passwordless sign-in that uses email and SMS as a means of distributing authentication links that allow users to verify 
their email/phone after they’ve had the opportunity to explore your product or service.
When you install the Rownd plugin for WordPress, you’ll bring our powerfully simple authentication and user account capabilities into 
your website, blog, or ecommerce site.
Rownd integrates with the existing WordPress user management system, which means we’re compatible with WooCommerce and many other 
WordPress addons! We’ll also detect whether you have WooCommerce installed and provide options to customize your customer experience 
during the checkout process.
Whether you’re accepting user signups already or want to start, Rownd makes it super-simple to get visitors and customers up and running quickly. 
Easily trigger our sign-in dialog by setting some HTML data attributes in your code or writing some simple Javascript and we’ll handle getting 
your users verified and signed in using our unique, passwordless approach.
To get started, you’ll need:
<ol>
<li>A free <a href="https://app.rownd.io" rel="nofollow ugc">Rownd account</a></li>
<li>A Rownd app key</li>
</ol>
Once you install this plugin, drop your app key and secret into our settings and you’ll be good to go!
Usage of this plugin is governed by Rownd’s <a href="https://rownd.io/terms-and-conditions" rel="nofollow ugc">terms of service</a>.
